Symptoms
Consider the following scenario:
-
You create a disclaimer transport rule in an environment that has Update Rollup 1 for Microsoft Exchange Server 2010 Service Pack 3 (SP3) installed.
-
The transport rule is applied to all messages, and appends some text to email messages.
-
The disclaimer transport rule tries to apply the disclaimer to an HTML-formatted message.
In this scenario, the HTML-formatted message cannot be delivered to recipients, and the EdgeTransport.exe process crashes on the Hub Transport server. Additionally, the following event is logged in the Application log:
Cause
This issue occurs because the message body and the disclaimer text use the same character encoding. This causes an issue in which a null charset parameter is called in the character encoding.

To resolve this issue, install the following update rollup:
